Children spend more time asleep than adults, and good sleep matters more at this stage of life than most people realise. The right mattress supports a growing spine, regulates temperature through the night, and holds up to the demands of active younger sleepers. At Land of Beds, we stock children's mattresses from brands including Simba, Silentnight, and Breasley, as well as our own Land of Beds range, covering foam, memory foam, and pocket spring constructions across small single and single sizes. Options start from under £130, and most come with next day delivery. Free mainland UK delivery is included on orders over £100.

Buying a mattress for a child is a different decision from buying one for an adult. The support requirements are different, the size range is smaller, and practical concerns, spillage resistance, allergens, and how long the mattress will last before the child outgrows it, matter in a way they do not for adult purchases. The good news is that children's mattresses are simpler to navigate than adult ones. The range is focused, the price points are accessible, and getting a few key decisions right will give you a mattress that does its job properly for several years. At Land of Beds, we have been helping families make this choice for over 50 years.
Three decisions shape whether a children's mattress is right for your child. Get these right and the rest follows.
| Factor | Why It Matters | What to Check |
|---|---|---|
| Size | Children's mattresses come in small single (2ft 6) and single (3ft). The right size depends entirely on the bed frame, the mattress must match the bed exactly. A small single is standard for toddler and junior beds; a single suits most children from around age 7 upwards and will last into their teens. | Measure the bed frame if you are unsure. See the size guide below. |
| Construction and firmness | A firmer to medium firm mattress is generally recommended for children, as it provides consistent support for a growing spine without the body sinking too deep. Foam and pocket spring constructions both work well; memory foam can be appropriate from around age 7. | Age of the child (see guide below); whether they share a bunk bed (mattress depth is important here); any known allergies |
| Practicality | Children's mattresses need to be durable enough for active sleeping and occasional spills. A removable, washable cover and a mattress protector will extend the mattress life considerably. | Does the mattress have a removable cover? Is it compatible with a waterproof protector? See our Mattress Protectors range. |

Children's mattresses come in two standard UK sizes. The mattress must match the bed frame exactly.
| Size | Mattress Dimensions | Best For |
|---|---|---|
| Small Single (2ft 6) | 75 x 190cm | Toddler and junior beds; children transitioning from a cot; compact children's rooms |
| Single (3ft) | 90 x 190cm | Most children from around age 7 upwards; bunk beds and cabin beds; a size that will last into the teen years |
If you have a bunk bed or cabin bed, check the maximum mattress depth allowed by the bed frame before ordering. Some bunk bed frames have depth restrictions for safety reasons. See our Bunk Bed Mattresses page for more on this.
See our UK Bed Sizes Guide for room-by-room measuring advice.
Children's mattresses are available in three main construction types. Here is a plain comparison of each.
| Type | Key Features | Best For |
|---|---|---|
| Foam | A single or multiple layers of supportive foam with no springs. Firm to medium firm. Lightweight and easy to move. Wipe-down or removable cover. Often the most affordable option. | Younger children and toddlers; bunk beds where mattress depth matters; parents wanting a practical, easy-to-maintain mattress at an accessible price |
| Memory Foam | A foam base with a memory foam comfort layer on top. Provides gentle body-contouring support. Generally suitable from around age 7. Medium tension. | Older children and teenagers who want more surface comfort; those who sleep restlessly and benefit from motion-absorbing foam |
| Pocket Spring / Hybrid | Individual pocket springs beneath a foam or memory foam comfort layer. More responsive than foam alone. Better airflow. Higher spring counts provide better support for heavier or older children. | Older children and teenagers; those who prefer a more traditional spring feel; children who sleep warm and benefit from better mattress airflow |
Getting the right firmness for your child's age and size makes a real difference to the support they get during sleep.
| Age Group | Recommended Firmness | Why |
|---|---|---|
| Toddlers (2 to 6 years) | Firm | Young children need a firm, flat surface that does not allow the body to sink. A firm foam mattress provides even, consistent support for a growing spine at this stage. |
| Children (7 to 12 years) | Medium firm to medium | As children grow heavier, a slightly softer surface becomes appropriate. Medium firm foam or a hybrid with pocket springs works well for this age group. |
| Teenagers | Medium to medium firm | Teenagers can generally use the same firmness guidance as adults. Sleep position becomes the main guide, side sleepers may prefer medium; back and front sleepers may prefer medium firm. |
If your child has a specific health condition or has been advised by a healthcare professional on mattress firmness, follow that guidance above all else.

Choose a Pocket Spring or Hybrid mattress if:
In our experience, most parents buying for younger children land on a firm foam mattress, it is simple, practical, durable, and does the job well for the early years. For children aged 8 and above, a hybrid with pocket springs is often worth considering as they are growing fast and will get years of use from a better-quality spring system.
Yes, and more so than for an adult mattress. Children are more likely to have accidents during the night, and a mattress without a protector can absorb moisture and harbour bacteria over time, shortening its lifespan and affecting hygiene. A good waterproof mattress protector is a practical investment that protects both the mattress and your child's sleep environment. Look for one that is breathable so it does not affect the feel of the mattress.

| Question | Answer |
|---|---|
| What size mattress does my child need? | It depends on their bed frame. Small single (75 x 190cm) is standard for toddler and junior beds. Single (90 x 190cm) suits most children from around age 7 and will last into their teen years. Always measure the bed frame if you are not sure, the mattress must match exactly. |
| What firmness is best for a child's mattress? | Younger children generally need a firm mattress that provides flat, consistent support for a growing spine. From around age 7, medium firm or medium becomes more appropriate as children grow heavier. Teenagers can follow the same guidance as adults, with sleep position as the main guide. If your child has been given specific advice by a healthcare professional, follow that first. |
| Can children sleep on memory foam? | Memory foam is generally considered appropriate from around age 7. For younger children, a firm foam mattress without a slow-contouring layer is a better choice, as it provides more consistent flat support for spinal development. The Simba Hybrid Kids mattress in our range is a well-regarded option for older children and contains appropriate foam and spring construction for this age group. |
| What is the best mattress for a bunk bed? | Bunk beds often have a maximum mattress depth specified by the manufacturer for safety reasons, the mattress must not protrude above the safety rail. Always check the maximum depth before ordering. Thinner foam mattresses are often the most practical choice for bunk beds. See our dedicated Bunk Bed Mattresses page for options suited to bunk beds. |
| Do I need a mattress protector for a child's bed? | Yes, more so than for an adult bed. Children are more likely to have nighttime accidents, and a waterproof mattress protector is one of the most practical investments you can make alongside a new children's mattress. It will protect the mattress from moisture and extend its lifespan significantly. Browse our Mattress Protectors for breathable, waterproof options. |
| How long should a kids mattress last? | A well-made children's mattress typically lasts 7 to 10 years, though children often outgrow a size before the mattress itself is worn out. Most options in our range carry guarantees of 5 to 10 years. A mattress protector will help it reach its full lifespan. |
| What brands do you stock for children's mattresses? | We stock children's mattresses from Simba, Silentnight, and Breasley, as well as our own Land of Beds range which has been developed specifically for younger sleepers. |
| Do you offer free delivery on kids mattresses? | Yes. Free mainland UK delivery on orders over £100. Many kids mattresses in our range also qualify for next day delivery, check the individual product listing for lead times. |
| Can I buy a kids mattress on finance? | Yes. Finance is available on eligible orders. See our finance page for details on available terms and how to apply. |
| What bed frames do you stock for children? | We stock a wide range of children's beds including bunk beds, cabin beds, mid sleepers, high sleepers, and standard single bed frames. See our Kids Beds page for the full range. |
